To @ZZ whom it may concern:

Be it known that I, CHRISTOPHER C. KING,

of Syracuse, in the county of Onondaga, in the State of New York, haveinvented new and useful Improvements in Coolers, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

This invention consists in a novel, simple,

ro and inexpensive construction of a cooler or refrigerator whichpossesses a great amount of refrigerating-surfaces formed of open-toppedtanks surrounding the central or main portion of the interior of thecooler and charged with the water derived from the melting of the ice,said tanks being so arranged as to cause the air to circulate in thecooler and pass over the surface of the water contained in the tanks,and thereby cause the water to 2o absorb the gases from the air, all ashereinafter more fully described, and specifically set forth in theclaims.

In the annexed drawings, Figure l is a perspective view of the exteriorof a cooler embodying my invention. Fig. 2 is a vertical transversesection on line a: w in Fig. l; and y Figs. 3 and 4 are horizontaltransverse sections, respectively, on lines y y and .e ein Fig. 2. 3oSimilar letters of reference indicate corresponding parts.

O represents the case of the cooler or refrigerator, which case is madeair-tight as near as possible. Large coolers-such as are used in 3 5meatmarkets-I provide with a door D, through which to obtain access tothe coma partment O', in which the meat or other substance to bepreserved is stored. .Another door D is provided near the top of thecooler 4c and a gate D in the wall of the ice-rack for the introductionof the ice.

a represents the ice-rack, which consists of an open net-work ot bars orslats mounted on cleats secured to the sides of the interior of the casea proper distance from the top thereof to allow the requisite quantityof ice to be placed upon the rack. Said rack is provided withsurrounding Walls a', which stand a suf iicient distance from the sidesof the case and 5o extend only part way toward the top of the interiorof the case to form vertical air-passages c up the exterior of theice-rack, and transverse air-passages e over the top of the rack, asindicated by arrows in Fig. 2 of the drawings. l

Immediately under the ice-rack is located the horizontal water-tank b,which extends across the main portion of the case C, leaving spacesaround the sides of the tank to form air-passages f f thereat. Beneathsaid tank is 6o a vertical tank c, which extends around the sides of theinterior of the case, as shown in Fig. 4t of the drawings. A sufficientspace is left between the top ofthe tank c and bottom of the tank b toform air-passages h h, which communicate with the passages e. Below thetank c is another tank d, which extends over the entire bottomof theinterior of the case C and has the Hoor Zsupported overa portion of itand lattice-work Z over the remainder of 7o the said tank to expose thewater contained therein to the air confined in the case. All of saidtanks are open at the top, so as to cause the water to absorb the gasesfrom the air in the case. Said tanks become charged with the cold waterdripping from the ice by the following overiowpipes: An overownpipe Pextends from near the top of the tank b into the subjacent tank c, andanother overdow-pipe P extends from near the top of the 8o tank c downinto the bottom tank d, to which is attached the waste-pipe P, havingits receiving end near the top of said tank.

In the operation of the described cooler the ice is placed on the racka. Theairin the cooler becoming therebychilled descends to thelower partof the cooler, and the Warmer being displaced in the latter ascendsalong the sides of the vertical tank c, thence passes across the top ofsaid tank and up along the exterior of 9o the tank b and walls a a ofthe rack a, and thence passes over the ice and down through. it to theinterior of the tank b, from whence it again descends through thepassages hh to the lower portion of the cooler. In the meantime thedrippings from the ice pass successively from the tank t) to the tank cand tank d and cause each of said tanks to be lled with ice-cold Water.The air in its beforedescribed circulation comes in contact with the roowalls of the tanks andwith the surfaces of the water contained therein,and this causes the air to be thoroughly chilled before it returns tothe ice, and therefore reduces the consumption of ice. At the same timethe water absorbs the gases from the air, and consequently the cooler isrendered very efficient and economical in its operation.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

l. The combination, with the case C, of the ice-rack a, located in theupper part of said case, the tank l) beneath the ice-rack to receive thedrippings from the ice, the tank c, extending around the sides of thecase, the overflow-pipe P, extending from near the top of the tank l)into the tank c, the tank d, eX- tending over the bottom of the interiorof the case, the overiowpipe P extending from near the top of the tank cinto the tank (l, and the waste-pipe P, having its receiving end nearthe top of the tank d, substantialT as described and shown. l

2. The combination of thc case C, formed air-tight, the ice-rack a,located in the upper part of said case and provided with surroundingwalls a', forming air-passages e and e', respectively, up the exteriorand over the top of the rack, the tank b, immediately under theaforesaid rack and having air-passages f f extending around itsexterior, the tank c, extending around the sides of the case and havingits top open and forming air-passages 7L h between its top and bottom ofthe tank l), the tank d, extending,r over the bottom of the interior ofthe ease, overiiow-pipes P and P', leading; successively from the upperto the lower tanks, and the waste-pipe P, having its receiving end nearthe top of the tank d, substantially as described and shown.

ln testimony whereof I have hereunto 4o signed my name this Sth day ofMarch, 1892.
